You cannot use the 551M S4 xdf for the 551M allroad file The addresses differ.

You can flash your car wth the 551L S4 file, that shares a definition file with the 551M s4 file, so the xdf you posted will work.

So I just need to do it all again using the s4 file base instead of the allroad file correct?  We talked about this last night and I forgot already.  Ugh.

For those interested. I was able to do my own check sums and it found 6 wrong and corrected them.  So I flashed it on my car. Upon cycling the key off then back on again my tip display was lit solid like limp mode. And my car would crank and not start. So it is not a good file.

Maybe cluster/immobilizer issues due to flashing mbox s4 to an allroad. Pretty new to all this but seem to recall reading about that.

Nope.  Wasn't an issue as b5 doesn't use an immo. And writing a b5 file to a allroad ecu won't change the immo in the allroad ecu.  If I changed the eeprom I could've had an issue.
